Sanrad
Centauri 0.30T MRI System
Super Open
Magnetic Resonance Imaging System
Wide bore ,Patient friendly .
In house music
Adopts Dynamic balancing
technology.
Best homogeneity ,<.9ppm.
Powerful Gradient System
 Gradient coil/ Amplifier
–Maximum gradient strength 18T/m ensure
high special resolution
–Rising time 600μs( up to 98%)
–Slew rate 55mT/m/ms increase the
scanning speed
 Thin slice thickness and less scan time.
Comprehensive Receiving coils
 7 standard Coil configuration：
QD Head coil
Shoulder coil
QD Neck Coil
Spine Coil
QD Body Coil
QD Extremity Coil
Abundant Imaging Sequences
 Spin Echo /FSE
 Gradient Echo（GE）
 IR, FLAIR, STIR
 MSME
 MRA/MRV
SS FSE
 MRU,MRCP）
DWI/ADC Mapping

Features of MRI
 Non-invasive examination
 Multi-type of images
 High image contrast
 Slicing at any orientation
 No contrast agent required in
MRA/MRV/MRU
Multi-type of images
 To get more diagnosis information by comparing various
images
 To improve diagnostic confidence and detection rate.
GRE Images
T2 Images
FLAIR Image
T1 image
Slicing at any orientation
Axial
Sag
Coronal
No Contract Agent Need in MRA
 In-flow and out-flow effect
 3D and 2DTOF

Clinical Applications
Body Morphology.
Spin Echo（SE)
 Bread and Butter
sequence
 Clear image
 For anatomic details
 Gives Good T1 wt
contrast
.
Fast Spin Echo (FSE）
 Used for T2 contrast.
 For better pathological details.
Gradient Echo (GE）
 Fast image acquisition
 Sensitive to bleeding
T2 Images
IR , FLAIR
 Water Suppressed
 Infarct/ tumor displayed
better
 Judge focal composition
IR, STIR
 Fat suppression signal
 Judge focus composition
 Other parts displayed much
clearer
MRA
 Angio without contrast
 2D/3D TOD
 MOSTE
 MTContrast
 MIP projection
 arterio and venogramme displayed
Carotid MRA
Venogramme
